PvP Season 11 Ending Soon

Arena and Rated Battleground Season 11 is scheduled to end on Wednesday, August 29. At that point, we will determine who is eligible for the end-of-season rewards, a process that should take approximately one week. It's very important for players who feel that they may be eligible for Arena titles and/or the Cataclysmic Gladiator’s Twilight Drake to refrain from transferring their characters to another realm or faction until after Season 11 ends. The awarding of Season 11 titles and mounts will occur approximately 1 week after the season ends.

At the end of the season, Conquest Points will be converted to Honor Points, possibly exceeding the 4,000 point Honor cap. There will be no cap on Honor until Mists of Pandaria is released on September 25. At that time, any Honor accrued above the 4,000-point cap will be converted into gold at a rate of 35 silver per point.

All Season 11 items will cost Honor Points (equivalent to their previous Conquest Point cost) when the season ends, with the exception of any items with rating requirements attached. These items will no longer be available for purchase.

The next Arena and Rated Battleground season will begin for level-90 players approximately one week after Mists of Pandaria launches. During the break between seasons, all Rated Battleground and Arena matches will be unavailable. Matchmaking (MMR), Team, and Personal Ratings will all be wiped when Season 12 begins.

I hope that "35 copper per point" was a typo. It should be silver, or else someone with 5000 excess honor will get 17.5g for it, which is probably less than one lvl 90 daily quest that takes 2 mins to do.
